I/ab. — Queensland: Carrawal and Mount Chalmers. 



Three specimens, including the sexes, received from Mr. 

 C. French, were at first determined by the author as A. 

 elli'psoides, Pasc. One specimen was sent to the British 

 Museum, and compared with the type by Mr. C. O. Water- 

 house, who very courteously took this trouble and writes that 

 elli'psoides is "blacker, longer, with the interstices of elytra 

 convex; yours is very near A. conve.rus, Pasc, but the an- 

 tennae are shorter and a trifle more slender, the elytra duller 

 and more green, the punctuation visible ; there is none in 

 conve.rus." A. convexus, Pasc, is a very common South 

 Queensland species, smaller, more nitid, the legs brighter-red, 

 and quite distinct from the above. 



Amarygmus rufescens, n. sp. 



Ovate convex ; head and pronotum nitid-black (with the 

 labrum and front and hind margins of pronotum reddish), 

 antennae, legs, and under-side red, tarsi pale-red, elytra 

 brilliant-purple, with coppery reflections at the suture and 

 green on the postero-lateral margins. 



Head closely punctate, eyes distant the length of the 

 first two antennal joints; antennae short and thin, scarcely 

 enlarged apically, joint three little longer than fourth, fourth 

 to seventh short and linear, eighth to eleventh narrowly 

 oval. Prothorax apex truncate, base slightly sinuate, sides 

 lightly arcuate, base about one and a half times as wide as 

 apex; finely, not very closely, punctate, without a medial 

 line. Scutellum large, triangular, metallic. Elytra rather 

 wider than prothorax, ovate; finely striate-punctate ; striae 

 shallow but distinct, the punctures therein small, placed at 

 a distance equal to the diameter of one, intervals flat (feebly 

 convex at the apex and sides) and minutely punctate. Under^ 

 side rather closely striolate. Dimensions — 5 x 2'8 mm.

A single specimen in the Macleay Museum is differen- 

 tiated from its nearest ally A. diayeroides, Blkb. (of which 

 I have ■ seen two specimens from the South Australian
